Chevelle Gauges

These conversion gauges are designed to fit into the EXISTING openings in the back of the dash. They include the Temperature sensing device and the mechanical Oil Pressure line and fittings. An ammeter* is standard, as was used by GM.

SHIFTWORKS ® conversion gauges are manufactured in the United States of America.

Replacing Factory Gauges??

The Factory Gauges dash was different than the standard dash. These Adaptors allow the use of SHIFTWORKS ® Gauges series #S505 to be used in the factory original gauges dash. Our gauges were designed to fit the standard dash, and these adaptors were made in response to requests from customers.

#S533 . . . Call for Price and availability. (702-895-6812) These original GM parts are now obsolete and no longer available from GM. We have limited stock of gently used and new units

The Temperature Sending unit should be located in the intake manifold near the thermostat. Some newer engines have sending unit locations that are inconvenient. This GM Water Neck can solve that problem.



Temperature Sending Unit
#S534 . . . $20.00

Use this Shiftworks unit if your engine requires a sending unit smaller than the ½ inch pipe thread-sized unit supplied. Our sending unit is 1/8 inch NPT and comes with a 1/2 inch NPT adaptor. A 3/8 inch NPT adaptor is available on request.
